Product Overview

The LM2575N-5.0/NOPB is a SIMPLE SWITCHER step down (buck) voltage regulator with fixed output in 16 pin DIP package. It provides all active functions required for step down (buck) switching regulator. This simple to use regulator includes internal frequency compensation and fixed frequency oscillator. The LM2575 offers high efficiency replacement for popular three terminal linear regulators. It substantially reduces size of heat sink and in many cases, heat sink is not required. A standard series of inductors optimized for use with LM2575 are available from several different manufacturers. This feature greatly simplifies the design of switch mode power supplies. This regulator also includes specified ±4% tolerance on output voltage within specified input voltages and output load conditions and ±10% on oscillator frequency. External shutdown function features 50μA (typical) standby current.
  • Fixed output voltage of 5V
  • Output current of 1A
  • Wide input voltage range from 4V to 40V
  • 52KHz fixed frequency internal oscillator
  • TTL shutdown capability and low power standby mode
  • Thermal shutdown and current limit protection
  • Excellent line and load regulation
  • Operating temperature range from -40°C to 125°C
  • P+ product enhancement tested
  • Requires only four external components


Power Management


This device has limited built-in ESD protection. The leads should be shorted or device should be placed in conductive foam during storage or handling to prevent electrostatic damage to MOS gates.
